into chucks of the buttonmaking machine,

are shaped and grooved after which they as may be desired.

It will be noted that there are apparently "1 a number of unnecessary steps in this method of making buttons, such as the preliminary formin of "the button material into discs or bla s, and then feeding such discs or blanks to the button making machine.

It has been found that very satisfactory buttons may be made from certain casein products, which products are adapted to be formed into rods of any desired length.

, It is an object of this invention to provide which buttons may be formed from rods 0 material, such as a casein prodnot, without necessitating preliminary forming of the material into discs or blanks, andalso eliminate the necessity of feeding such blanks to a button making machine.

A further object of the invention is the provision. of a machine by which buttons may be made from a rod-of material such as a casein product, without requiring theservices of an attendant, the buttons being formed and the material fed to the machine automatically, I

A further objectis in the provision of a device in a button making machine whereby a facing tool may be periodically fed forwardly and *broughtinto contact with an abrasive to maintain a sharp edge on said tool.

These and other advantages, which will later appear, are accomplished by the simple and practical construction and arrange- I ment of parts hereinafter describedand exhibited in the] accompanying drawings,

so forming part hereof, and in which: fl,

Figures 8, 9 and 10 show the sequence of steps in forming a button by my machine.-

Referring to the drawings, in Figure 1,. the machine is shown to have a base 1, with an upstanding main support -2. J ournalled in bearings 3 and 4 on the base, is a shaft 5, adapted to be driven by a belt 6. The shaft carries a worm 7 in mesh with a worm wheel 8, the latter being fixed to a shaft 9, which is journalled in a bearing 10 integral with the main support 2 and having also fixed thereto the cam discs 11, 12, 13, 14, and 15.

The cam disc 12 is engaged by a rocker 16 v pivoted on a shaft 17 journalled in a bearing on support 2, the rocker having an apertured arm 18 through which passes a pin 19 having a flange 20 adapted to be engaged by' arm 18 when the latter is moved forwardly as shown in Figure 1. ,The-pin 19 is connected with a bell crank 21 rotatably mounted in a bracket 22 on the support 2.

The arm 23 of the bell crank passes through an-aperture in a block 24 integral with a rod 25, the latter being guided vertically by the bracket extensions 26 and 27, and normally urged downwardly by a co-mpression spring 28 hearing against the block 24 and the guide 26. The lower end of rod 25 is provided with an integral block 29 in which is journalled a rotatable ine-mber 30' and which, at predetermined times, comes into the ath of the rod of casein material 30 to limit the forward movement of the latter when it is released so that it may be forced forward by the action of the weight 31 which constantly urges the rod 30 in that direction. The weight 31 is connected to a cord 32 which passes over a pulley 33, the

cord being connected to a member 34, which slides in a groove and bears against the rear 5 end of rod 30.

Cam 11 is engaged by the bell crank 35 pivoted to the support 2 at 36, the bell crank 35. having an arm 37 pivoted to a link 38, the

latter being connected to arm 39 of a bell 10 crank fixed to shaft 40, which is rotatably mounted in bearing 41 mounted on the support 2. The other arm 42 of the bell crank is offset and has mounted thereon a cutting tool- 43 for rounding the edges of buttons. The tool 43 is constantly urged towards an operative position by a tension spring 44 fixed to the bracket 27 and the arm 39.

The cam 14 is engaged by the arm 45 of a bell crank pivoted at 46 to the support 2. The arm 47 of the bell crank is pivotally connected at 48 to a link 49, which in turn is pivotally connected to arm 50 fixed to a shaft 51 journalled in a bracket 52 mounted on support 2. 35 Integral with arm 50 is a depending arm 53 which has at its lower end a bearing 54 in which is 'ournalled a shaft 55, the latter having fixed thereto a circular saw 56 and pulley 57 by means of which the shaft may be driven by belt 58. i The rod 49 is normally urged downward by the pull of a tension spring 59 attached'to arm 47 and the base 1.

Cam 15 is engaged by arm 60 of a rocker pivoted at 61 to support 2, the other arm 62 of the rocker having journalled in its extremity a shaft 63, to which is fixed an arm 64 connected b a link 65 to the arm 66 of a rocker pivotal y mounted at 67 to the support 2, the rocker having an arm 68 engaging cam 13.

The arm 62 has a projection 69 on which is rotatably mounted an abrasive wheel 70, the latter bein driven b a belt 71. The abrasive wheel 0 is for t e purpose of sharpening a facing tool 72 clamped in a holder 73 fixed to shaft 63. I

The tool 72 consists of a flat strip of cutting metal and is held securely against the base 74 of the holder by means of a member 75 fixed at one end to a pin 76 projecting from shaft 63, and a clamp 77 embracing the base 74, holds member 75 tightly against the tool to prevent accidental slipping of the latter.

After each facing operation the tool 72 is fed forwardly and then tilted into engagement with the abrasive wheel so that the edge of the tool 72 is maintained sharp. The tool is intermittently fed forward by means of 3. lug 78 engaging its rear end. (SeeFigures 5 and 6.) i

The lug 78 is integral with an internally threaded block 79 mounted on a threaded shaft 80 having its ends journalled in the 55 base 74., The lug 78 projects upwardly shaft 85 journalled in the walls of the tool holder 73. The shaft 85 is journalled in a link 86 and has fixed thereto a ratchet 87,

which cooperates with. a pawl 88 to rotate shaft 85. 'The pawl 88 is pivoted to link 86 and is held in engagement with the ratchet by means of a spring 89 connecting the extremities of the pawl and the link 86. An arm 90 projects upwardly from the extremity of the arm 62, and is connected to the upper extremity of link 86 by means of a link 91. It will be seen that the portion of holder 73 between shafts 63 .and 85, with link 91 constitute two ,sides of a parallelogram; the link 86 and the arm 90 constituting the other two sides. Since arm 90 is vertical and fixed, obviously changes in the angularity of link 91 and holder 73 will cause slight rotary movements of their extremities. For example, when cam 13 causes counter clockwise rotation (see Figure 2) of arm 68, the tool holder 73 is moved upward to ahorizontal and operative posit-ion. During this movement the pawl 88 ratchets over the ratchet wheel 87. 'As the cam 13 continues to rotate and allows arm 68 to rotate clockwise, the spring 92, fixed to holder 73 and the base 1, pulls the holder 73 downward so that the tool engages the abrasive Wheel 7 0.

During the downward movement, the change in angularity of the parallelogram causes a tooth of the ratchet wheel 87 to bear against the pawl 88, and the resistance of the latter rotates the wheel 87 and the shaft .85,'w hich in turn causes rotation of i the threaded shaft 80 through the worms 84 and worm wheel 83. Rotation of threaded shaft 80 causes lug 78 to feed the cutting tool 72 forwardly 1nto a position to be sharpened by the abrasive wheel 70.

J ournalled in bearings 93 and 94 integral with the support 2 is a shaft'17 having fixed to one end thereof a crank arm 96,

which is positioned inthe path of a lug 97 integral with or fixed to the cam disc 15. (See Figures 2 and 4). Also fixed to shaft 17 is a collar 98 having integral therewith a yoke 99, thelatter being adapted to engage a flange 100 integral with a clamping cylinder 101 rotatably mounted in the stationary casing 102, the pulley 103 being also integral with the cylinder 101 and rotating therewith, the pulley being driven by a belt The cylinder 101 is provided with a second flange 105 to receive pressure from a ,com-

pression spring 106 which also bears against a thrust bearing 107 adjustably fixed to the casing 102 by means of set screws. 108. The spring normally urges the cylinder 101, which has a tapered 0 ning, into wedging engagement with the c uck 109 to cause the latter to tightly hold the rod 30 of'casein material from which the buttons are made. When crank arm 96 is engaged by lug 97, the cylinder 101 is forced rearwardly against thepressure of spring 106, and the chuck is released to allow therod 30 to be moved forwardly by the action of weight 31 and member 34, In operation, the cam discs 11, 12, 13, 14 and 15 rotate counter-clockwise, i; e., in the direction of the arrow shown in Figure 2. The first movement of the machine in the formation of a button is the action of cam 12 on arm. 16 to allow spring 28 to cause the rod 'to descend to place-the block 29 in the path of the rod 30 to limit the forward movement thereof. Immediately thereafter the lug 97 passes from engagement with arm 96-and the spring 106 forces the cylinder 101 forward to cause the chuck 109 to tightly grip the rod 30.

Almost simultaneously, the cam 11 moves to a position to allow spring 44 to draw the edge shaping tool 43 into engagement with the rod to shape the under side and edges of the button as shown in Figure 8. While this is taking place, cam '12 has acted on arm 16 to cause-rod 25 to be raised, and cam '14 acts upon arm 45 13 has acted on rocker arm 68 to move the facing tool 72 to a horizontal position and cam 15 rotates rocker arms and 62 to move tool 72 into engagement with the end of rod 30, whereupon tool 72 performs the faclng operation as shown in Figure 9.

During the facin operation, tool 43 is being moved away from the rod, and cam to allow spring 59 to cause the circular saw 56 to be brought into engagement with the rod to sever the now pgnsipletely formed button. (See Figure 73Duringthe sawing operation, tool holder in engagement with the abrasive wheel 70, and the tool is fed forward slightly by action of the mechanism connected with ratchet wheel 87 and pawl 88, and the sequence of movements is repeated for the next button. 1 It will be seen that the rod 30 is first released so that it may be forced forward,

. and block 29 is placed in the path of the rod at the proper time to limit the forward movement of, the rod, then the bottom and edges of the button are formed, then the face of the button is formed, and finally it is severed by the circular saw.

- Mounted on a shelf 204 is an electric motor 202. having an abrasive wheel 203 fixed to the shaft thereof. From time to time the is being tilted downward to place the tool as descriptive and illustrative only," and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications without departing from the general scope herein indicated and denoted in the appended claims.
